Being red-orange in color, this predator is easy to identify. It is about
0.5 mm in length, and is rather quick-moving (like many predators).
and other web-spinning spider mites in
the family Tetranychidae.
The P. persimilis is a fast-moving predatory mite.
It searches leaf surfaces for webbing of pest
mites. Once finding webbing it will intensify its search for
eggs, larva and adult two-spot mites.
It then will consume all life stages
of pest mite. Prey consumption is up to 7 adult spider mites or 20 eggs
of its prey, the female P. persimilis lays its own eggs
within the strands of silk, where her young will hatch and continue to
feed. A well fed female will lay
about 50 eggs in her lifetime. Their life
cycle takes as little as 7 days, shorter than that of the pest mite prey
species. This is why P. persimilis is such a successful
predator. Once the 2-spot mites are gone, P. persimilis
will literally starve to death because they cannot live on any other
food. Ideal temperature range is
20-30șC with relative humidity of 70-80%. Minimum temperature for
activity is 10șC.
